What is the study of living organisms called?

The study of living organisms is called biology. This field encompasses a wide range of topics related to living things, including their structure, function, growth, evolution, distribution, and taxonomy. Biology can further be subdivided into various subfields such as zoology, botany, microbiology, and ecology, among others.

Physics and chemistry, while essential scientific disciplines, focus on the properties and interactions of matter and energy, as well as the composition, structure, and changes of substances, respectively. Ecology, on the other hand, is a branch of biology that specifically studies the interactions between organisms and their environment, making it a subset of biology rather than a separate study of living organisms as a whole.
